Multiple evaluation

When multiple evaluation is active, an object has to be scanned several times consecut-
ively before the safety laser scanner switches the OSSDs to the OFF state. This reduces
the probability that insects, welding sparks or other particles lead to a shutdown of a plant.
If a multiple evaluation of 4 is configured, an object has to be detected 4 times in succes-
sion in the safety zone, so that the safety laser scanner switches the OSSDs to the OFF
state.
With a multiple evaluation > 2 an allowance has to be made to the response time. The
height of the allowance (see
the value of the multiple evaluation and the valid response time (see

Monitoring of reference outlines

An outline within the area covered by laser beams can be defined and monitored in
PSENscan Configurator as a reference outline. The outline is formed from reference points.
When PSEN sc M 3/5 series detects a change of the outline, the safety laser scanner
switches the OSSDs to the OFF state.
